OK, let's get the main thing about this book out of the way - it doesn't do pictures. It has some pictures in a glossy introductory section and then it's text all the way. If you feel the need to be shown a picture of something before you go and see it, you won't like this book.
If you're happy reading text however this book is one of the best travel guides I've used for any region. It's written with an infectious and genuine enthusiasm for the region, and includes a very accessible guide to its history. It includes little snippets on certain elements of Andalucian life as well, and most useful of all some very instructive pieces on Moorish art - I don't think I would have enjoyed the Alhambra nearly as much without this indepth and accessible introduction.
I am one hundred per cent a fan of this book, but if you're not convinced ask yourself this. Would you rather a book that showed you a picture of the Mezquita's red and white arches before you went to see them for yourself, or a book that explained the significance of the design and its history so you could appreciate them more when you went? This is the latter. This book made my trip, and with its help I came back with a lot of excellent pictures of my own.
